They were showing this at JB Hifi and i just figure it's it's better motion adaptive interlacing and cadence detection rather than "real" motion enhancement. It would be cheaper to turn off the processing and get it done on a HTPC with a graphics card.
I never got what these "HZ" boosters ever did except increase the screen refresh rate and reduce eye stress due to perceived flicker. Technically you have a source with a 24 to 60 Frames per second of image data. The only way you can actually fill up a refresh rate of 200HZ is to interpolate data, but raw image and motion data can't be interpolated with current hardware on the fly, so it's generally down to the CODEC to do so. The youtube demonstration in my opinion is misleading, because the source does not change, it's still 24 to 60 FPS. So conclusion is that these TV sets generally just, repeat frames at set intervals, which is actually...well pretty lame. And heck interpolation actually ruins some most movies because FPS is chosen specifically by the director and enhanced during post production to further the effect, watch the Dark Knight for a good example of this. I swear TV company are going to have to deal with consumer lashback one of these day for lying through their teeth about such simple things. Granted, "new algos" isn't impressive as a marketing tagline |

empire, motionflow is frame interpolation (creation of a "intra" frame) .. (doesn't repeat same frame that would be same frame insertion)
saw it in action (the "Z" 200hz one anyway) last weekend at a sony store , watched on a few BD titles.. movies shot on film with 24fps looks "fake" in a non-film kind of way, when this feature is turned on.. like it's shot on HD digital video cams for TV series (or low end movies).. Ok, it looks surreal like real life (some will like it, so can't really speak for others whether its better or not) but I believe it would look good on video sources other than film but nothing to demo it on dat day. and since most of my BD material is 1080p24 film based (except for Crank and those Nat Geo/planet earth/BBC stuff) then I can see myself turning off this feature more often than not.

(doesn't repeat same frame that would be same frame insertion) There's 2 ways you can do interpolation IIRC, looks like that old man babling about it all day was useful after all (thanks Bruce)one is time based interpolation, where you insert the same frames, but at varying time lenghts to give a better perception. one is composite, which means you calculate 2 similarly likely frames and composite em together. Both aren't good for movies in my opinion, both are in fact not "real" interpolation, and both are really "Cheap" methods to increasing perceived motion PQ and bring nothing new to the table. It's not like they didn't do the same for 120HZ and hell that wasn't even impressive. And before i forget, they ruin the crank and slow effect directors often employ in movies, much to my chagrin.

Haha, the dreaded sitcom effect.

Frame interpolation is generally not intelligent enough to see where the director is using an effect to better portray a scene, blame unintelligent math lol. I used the Dark Knight as an example because it's quite evident in the Imax scenes. Which reminds me.....i always wanted a specialized video processor that could read off a movie profile to tailor the processing for max enjoyment. Sad it applies only to games for now. |

Its BEST, One U new wing, top floor. hahaha.. always make mistake cos their shop concept looks the sameThe whole objective of this thread is lost when it comes to folks like you. This is never about who has the bigger e-penis, it is always about Sony's Motionflow and how it effects even non-SD materials. But hey, your's longer right? Which SenQ? I whisper a prayer of thanks every time I see HDTVs being portrayed as they are supposed to, with connection to the right sources, and displayed for its strengths. Some showroom just simply want to push TVs without thinking of properly setting them up to allow potential buyers to objectively judge them without bias. All they do is pump up the setting to "Vivid" and hope the buyers gets blinded by the colorful colors and blinded into buying them as well. I for one am not asking them to even go towards proper calibrations for their TVs, it is after all, their job to sell TVs, but at the very least, display them at their proper strength and not overblown them with colors so red, you can see it bleed out of the screen, or so bright, I got "blinded by their supposed awesomeness" , to quote Po, the Kung Fu Panda. Buying a TV is of personal experience, some buyers prefer certain characteristics only offered by certain TV types, plasma or LCDs, and later OLED and Lasers. I've seen Sony's OLED screens and the Mitsubishi's LASER HDTVs in showrooms in Osaka and Tokyo, and each and every one of these types offers their own strengths and weaknesses. It is up to the buyer to go for their pros and live with their cons. Even within a particular TV type, there are comparable differences between them. Samsung LCDs tend to display a more blue bias than others, while Toshibas and Sharp colors are warmer in comparison. Sure you can calibrate these out, but it all comes to the personal preference and choice of the buyer itself. |

Did Best Denki just dropped their "Denki" moniker, and stick with the first word? Easy to get mistaken though, now every stores look the same, be it Harvey, BEST, or SenQ. Same ID perhaps? |

QUOTE(Sony Trinitron @ Jan 30 2009, 11:34 PM) There's always turning off the Motionflow lol Solution Attained. My advice would be to put a priority on the IQ of the LCD panel first (including the back lighting), the IQ of processing second and all other gimmicks 3rd. I has Avivo which has perfect HQV HD scores, so i'm only worried about no1. |

![]() Will somebody get Professor Emmett Brown back to his cage before he fries anyone with his 1.21 Jigawatt brainstorming ideas? Watching Astro, particularly EPL matches does not benefit fully from the Motionflow technology., thanks to the abysmal quality of the Astro transmission. Instead of a blurry mess that of a player running up the field, all Motionflow can do is clean up the mess and soften it up, so you'd get a nice, clean mess. The clarity wasn't there to begin with, so no matter how much the TV tries, it still cant compensate for the abomination that is Astro transmissions. |

The clarity wasn't there to begin with, so no matter how much the TV tries, it still cant compensate for the abomination that is Astro transmissions. I think the fact here is simple, motion flow is generally a cheap gimmick to sucker people, it's the same as when the 100HZ TV screens came out, same with the 120 HZ LCDs and so on. It is teh sux, but dolts like big numbers and catchy tag lines. It's like saying my Ipod has "Negative Feedback", "Loop technology" and "Low Z input", when they're all just fancy words to describe a wire and 2 resistors connected from in to out. Lesson is, don't fall for the marketing hype. And before someone tells me "you have to see it for yourself, thus you have to buy the damned thing first!", shut ye pie hole, i already have too many monitors here and hell i don't even watch TV except for maybe 9 News and lousy documentaries on SBS and heck, what they've done, the glorious powers of the FPU processing have done years ago. It doesn't do much for shitty TV and screws some good movies. I think the point stands for itself and it's what i've been trying to state here. You want a discussion on Motionflow, well there it wasss. |

A different take on the Z, from CNET Australia. This Z is still so new, that reviews are hard to come by.
http://www.cnet.com.au/tvs/lcd/0,239035307,339293509,00.htm QUOTE Like most of the full-HD screens we've seen in the past year, the KLV-46Z4500 is particularly comfortable with 1080p content — it hearts teh Blu-ray discs! We found plenty of good detail and contrast on the troublesomely grainy and dark MI:3, and also found that the TV's 24p mode worked perfectly. Almost zero judder with MotionFlow off, and none at all with it on. You see, despite our initial cynicism about the new MotionFlow technology, it actually works quite well. At its highest setting motion can be a little too smooth — almost dizzyingly so — with the haloing artefacts we're used to. However, after testing Standard mode on many different types of content — free-to-air TV, DVD and Blu-ray — we found that it was good enough to leave on all the time. This is the most natural motion technology we've yet seen. But that said, we wouldn't buy it just for this. We believe it's up to the television stations and movie studios alike to combat judder — your TV shouldn't have to do it. The tuner's off-air performance was impressive with bold, colourful images. Initially we found some problems with smearing, but after disabling the set's noise reduction we found that the had problem stopped. When viewing the television off-axis, we found it performed quite well, with minimal discolouration, although it's not up to the standard as the Panasonic Viera TX-37LZD800A. There are still some rainbow polarising effects on dark scenes and a slight loss of contrast when viewed from the side. DVD performance was very good, though we have seen better. Colours were natural, black levels high, and detail good, though there was some minor noise discolouration in King Kong in the clouds and the river in a climactic scene. Performing our suite of synthetic HQV tests we found a familiar pattern among full-HD TVs — 1080p content passed with flying colours, while standard-def picture processing fell down when testing for jaggies. While the speakers may look better than the ones on the XBR45, they're unfortunately not as good. The XBR's have an extra bass woofer, leaving the Zed with a muddier, less hefty sound. But when compared to other sets they're as good as you can expect from any Sony TV. We were particularly taken with the SRS surround system and its effects during the King Kong DVD in the scene where the planes circle the Empire State Building. Quite impressive. If you have a home network, you'll find the Bravia is able to stream content quite easily. We used a PC with Windows Media Player 11 and sharing turned on. The Sony recognised the computer straight away and we were able to play MP3s and JPEGs without fuss. However, we found the TV wasn't very successful with music: playing the new David Byrne/Brian Eno collaboration left the TV a little throaty when trying to reproduce the ex-Talking Heads man's vocals. Photos, on the other hand, looked great courtesy of the TVs "Photo" picture mode. Despite some misgivings about the cosmetics and dubious marketing, this is a very likeable television. It performs well, it's relatively good value for money, and is loaded with features — including the supremely efficient 200Hz mode. If you're umming and ahhing between this and the XBR45, then it's a no-brainer — get this one. Bear in mind, this is the Z4500 version, is which the Malaysian Z450 is based of, minus the USB and Ethernet port and built-in HD tuner. |

In the areas of audio, people always argue with reason of acquired taste, it's an argument used >9000 times over, and the usual answer is that if you're fed shit everyday, eventually it becomes tolerable and in some cases acceptable. Doesn't mean it's good. But like i indicated in the first post, like the same techs before it, it's a gimmick. Soon enough there'll be a 400 HZ screen with the same features. Any different? Probably not. If you bought the TV for the panel quality and other features, cool, but thread's theme was on motion flow and put my 2 cents in. This is a forum, not your playbox where everyone's your yes man. I understand that people have the need to "defend" their purchases, we all don't like buying lemons, or finding out we bought lemons, sure even i got defensive when i bought the craptastic X1800XT lol, but you seem to take this insult to a new level, pray tell.... |

another review of the z series : hdtvtest.co.uk
http://www.hdtvtest.co.uk/news/sony-kdl40z...20081124136.htm Conclusion The deep blacks, accurate colours and low input lag on Sony’s latest high-end (W series and above) LCD HDTVs need no further praise, so we’re left to comment on the Sony KDL40Z4500’s 200Hz Motionflow implementation. The good news? There are surprisingly few kinks for what effectively is the first incarnation of 200Hz MCFI technology. Now the not-so-good news: any resultant improvement in motion clarity isn’t really leaps and bounds ahead of what 100Hz LCD televisions currently offer when it comes to real-life viewing. So while the Sony KDL40Z4500 holds the current record for the highest motion resolution we have measured on an LCD TV so far, pound-for-pound we think that the Sony KDL40W4500 (equipped with 100Hz Motionflow) represents better value-for-money. |
